LIFT TOW OF THE STRYKER
WARNING
Wheels on the towed vehicle should be chocked and parking brakes engaged prior to
beginning lift tow connection. Failure to comply could result in the vehicle moving
unexpectedly creating a crush hazard causing serious injury or death to personnel.
When performing front lift- tow of a STRYKER with rear axle damage or rear axle tie
up, the fuel tank to ground clearance must be monitored. Dragging the fuel tank could
cause leaks, creating environmental hazards, or a possible fire hazard. Failure to
comply could result in damage to the equipment and/or injury or death to personnel.
CAUTION
Use of the FWTRD to tow a disabled STRYKER shall be used to move it to the closest
available TDRT loading point. The remaining distance to the maintenance facility will
be facilitated by using the TDRT. Failure to do so may cause additional damage to the
STRYKER.
All damaged tires or axles making contact with the ground should be secured prior to
towing with FWTRD. Refer to TM 9-2355-311-10-1-1, WP 0045 00 for specific
instructions. Failure to comply may result in further damage to the equipment.
When lift towing, the STRYKER hull should be kept as level as possible. This is to
prevent overloading of the STRYKER axles. Failure to comply could cause further
damage to the vehicle.
NOTE
This work package refers to using the FWTRD independently to tow the STRYKER. If the
TDRT is also needed to transport the STRYKER, refer to WP 0012 00 and WP 0012.1 00
for instructions regarding loading the STRYKER on the TDRT.
These instructions describe the steps involved in lift-towing a STRYKER that has
suspension components in place that allow for use of the Stryker Adapters at the front
A-arms and the chaining of the FWTRD boom extensions to the second A-arms of the
STRYKER. If the STRYKER is missing any of these components then refer to WP 0011 00
for instructions on winching and sledding hook-ups for extreme conditions.

NOTE
Optimum height is lowest level STRYKER can be towed without hull interference over
obstacles and rough terrain. Keep the STRYKER hull as level as possible to avoid axle
overloading. The Booms should not be pinned beyond the second hole for lift towing a
STRYKER for any distance. The Booms of the FWTRD are designed for and may be
dragged over obstacles if necessary for short distances when pinned so that the Stryker
hull is level.
If the STRYKER suspension system is damaged the hull of the STRYKER may rub on the
tires during lift tow. To prevent this, the FWTRD BII includes cones that can be placed
over the individual suspension snubbers. These are located on the 3rd and 4th axles
behind the tires of the STRYKER. Steps 13-16 describe placing the cones. If the suspension
is intact, and the tires do not rub on the hull, skip to step 16.

FWTRD 18K WINCH OPERATIONS
SCOPE
Personnel should be trained (ASI H8) in recovery concepts before performing winching operations.
FM 4-30.31 Recovery and Battle Damage Assessment and Repair, and FM 5-125 Rigging Techniques,
Procedures, and Applications should be referenced for recovery doctrine.
There are several winching configurations for the FWTRD. They are as follows:
1. The XM20 FWTRD has the ability to use three winching options. Two are mounted onboard
and one utilizes the prime movers heavy winch. They are for use in various situations
including pulling vehicles onto the FWTRD booms, Recovery Winching, and winch loading
the TDRT (Tilt Deck Recovery Trailer).
a. The first option is the 18K winch mounted between the booms for pulling rolling
vehicles onto the booms from level areas or assisting when off-loading the TDRT.
b. The second option is the 35K winch. This can be used independently utilizing the winch
controls of the FWTRD. A diverter that is placed on the FWTRD allows the operator to
choose between the 18K and 35K winch. The operator then uses the FWTRD winch
control lever to operate the chosen winch. When using the 35K winch in this mode it
would be possible to set the FWTRD at 90 deg. to the prime mover for side slope winch
recovery.
c. The third option is to utilize the 45K winch of the prime mover through the winching
sheave of the FWTRD. In addition the 35K winch can be joined to and utilized in
conjunction with the 45K winch for heavy recovery situations. In this case the 35K winch
would be controlled by a valve that is mounted at the winch control station of the prime
mover.
NOTE
This work package gives steps in the use of the 18K winch that is part of the Fifth Wheel Towing
and Recovery Device (FWTRD).

FWTRD 18K WINCH OPERATIONS – Continued
WARNING
WINCHES
All personnel must stand clear at a distance equal to the length of cable during
winching operations. A snapped cable or shifting load could strike personnel causing
injury or death to personnel.
The 18K (FWTRD) winch does not have an internal brake to hold back a vehicle and is
not designed for recovery of vehicles in mired conditions. It is for moving vehicles on
level ground. Use only the 35K winch or a prime mover mounted 45K winch for
recovery operations. Failure to comply may result in death or injury to personnel.
WIRE ROPE
Wire rope can become frayed or contain broken wires. Wear heavy leather-palmed work
gloves when handling wire rope. Frayed or broken wire can injure hands. Never let a wire rope
slide through hands, even when wearing gloves. A broken wire could cut through glove and
cut hand.
Refer to FM 5-125 or FM 4-30.31 for inspection of wire rope. A damaged wire rope, under
load, could fail suddenly and strike personnel, and could cause the vehicle being recovered to
shift suddenly creating a crush hazard. Failure to comply can result in injury or death to
personnel.
WARNING
Wheels on the towed vehicle should be chocked and parking brakes engaged prior to
rigging winch cables. Failure to comply could result in the vehicle moving
unexpectedly creating a crush hazard causing serious injury or death to personnel.

18K Offload Assist for the TDRT
The following steps are for using the 18K winch to assist in the off load of a non-rolling
vehicle from the deck to the Tilt Deck Recovery Trailer (TDRT). If the disabled vehicle
rolls, it is not necessary to use the 18K winch to assist.
WARNING
The 45K or 35K winch should always be connected to the disabled vehicle when
offloading the TDRT. When using the 18K to assist offloading a disabled vehicle, failure
to have the 45K or 35K controlling the decent down the trailer deck could result in a
disabled vehicle suddenly moving freely which may result in death or injury to
personnel and or damage to the equipment.
CAUTION
Perform the setup of the 18K winch for offloading assist when the TDRT deck is still
level, prior to sliding the axles for tilting. This reduces the chance of the disabled
vehicle shifting suddenly creating a crush hazard. Failure to comply may result in
injury to personnel.
1. Attach the 18K snatch block to one of the tie down rings at the rear of the TDRT.
2. Free spool the 18K cable and bring it through the fairlead on the headboard of the TDRT (figure 4),
down through the snatch block, and then back toward the head of the TDRT and secure to a tie
down point on the disabled vehicle. (Figure 5) (The distance from the snatch block to your tie down
point is the distance you will be capable of moving the vehicle down the TDRT deck once tilted.)

CONFIGURING THE FWTRD 35K WINCH FOR TANDEM 35K/45K WINCHING OPERATION
NOTE
These steps apply to configuring the 35K winch for use with and operation from the
prime mover’s 45K winch control station. They would only be performed if you were
using the 35K winch in tandem with the prime mover 45K winch. Refer to TM 9-2320340-10 for M983A4 LET 45K winch operation.
WARNING
Hydraulic pressure from the prime mover can reach 3000psi (20 684 kPa) when using wet
lines. Never connect or disconnect hydraulic wetlines without ensuring that the prime mover
PTO is in the “off” (disengaged) position and engine of the prime mover is off. Should lines be
disconnected with the PTO “engaged”, over pressurizing the system could result, causing lines
or fittings to burst and hydraulic oil to spill creating a slip hazard. Failure to comply could
result in damage to equipment and serious injury or death to personnel
CAUTION
These procedures require the operator to be certified on the operation of the 983A4 LET
and its winching controls. Failure to comply may result in injury to personnel and damage
to the equipment.

RECOVERY WINCHING WITH THE FWTRD
WARNING
Winching and Recovery procedures outlined in this chapter should be performed by
personnel trained in the operation of the FWTRD. Failure to know and understand the
operating principle of the FWTRD could result in death or serious injury to personnel.
WINCHES
All personnel must stand clear at a distance equal to the length of cable during
winching operations. A snapped cable or shifting load could strike personnel causing
injury or death to personnel.
Unless a specific winch is indicated for a particular procedure, these instructions can
be performed with the prime mover 45K winch or the FWTRD 35K winch. The operator
should make the proper assessment of the situation in accordance with FM 4-30.31,
“Recovery and Battle Damage Assessment and Repair” in order to determine the
proper winch needed for the recovery. Failure to comply may cause injury or death to
personnel and or damage to the equipment.
The procedures outlined in this chapter refer to using heavy duty winches (45K or 35K)
in conjunction with the FWTRD. The 45K and 35K winches are the primary recovery
winches. The 18K winch on the FWTRD has limited capacity and should not be used for
recovery of vehicles. Failure to comply may cause injury or death to personnel and or
damage to the equipment.

Recovery Winching with the FWTRD - Continued
WIRE ROPES
Wire rope can become frayed or contain broken wires. Wear heavy leather-palmed
work gloves when handling wire rope. Frayed or broken wire can injure hands. Never
let a wire rope slide through hands, even when wearing gloves. A broken wire could
cut through glove and cut hand.
Refer to FM 5-125 for inspection of wire rope. A damaged wire rope, under load, could
fail suddenly and strike personnel, and could cause the vehicle being recovered to
shift suddenly creating a crush hazard. Failure to comply can result in injury or death
to personnel.
NOTE
Refer to the proper TM for the prime mover as well as FM 4-30.31, “Recovery and Battle
Damage Assessment and Repair” in conjunction with these instructions for additional
information relating to rigging, winching and recovery.
These instructions are specific to the XM20 FWTRD. The M250 FWTD does not have a
winching sheave mounted on it for recovery winching.
The following operation assumes that the FWTRD is in the transport configuration.
(WP 0007 00)
Assess the situation using “R.E.C.O.V.E.R.Y.” method as described in FM 4-30.31 section
4-14. This will determine whether you are using the 45K or 35K winch with the FWTRD,
and the mechanical advantage (MA) needed to complete the recovery (single, two-part
line, etc.).

Recovery Winching with the FWTRD - Continued
1. Position prime mover so that it is in direct line with and backed up to the disabled vehicle at
distance that allows the FWTRD Booms with boom caps to engage the ground.
WARNING
The Boom Caps weigh 40 lbs each. Caution should be used when removing and
handling the Boom Caps. They are installed on the booms when the FWTRD is in
transport configuration and if not properly secured could fall off, striking personnel,
causing injury or death.
NOTE
Boom Extensions must be fully retracted when installing Boom Caps. The wing bolts
used to stow the boom caps should be replaced in fifth wheel section for safe keeping.
(figure 1)
2.
Install Boom Caps by sliding over end of booms and securing with attached safety chains to D-Ring
on end of Boom.

Recovery Winching with the FWTRD – Continued
3. Follow steps 2-16 of WP 0011.1 00, FWTRD 35K Winch Operation, to install and bring the winch
cable down to the operator.
NOTE
The receivers and wheel stops should be positioned on the booms for the disabled
vehicle that is being recovered (WP 0010 00 step 3). (If recovering the STRYKER, refer to
WP 0010.1 00 for installing STRYKER adaptors.)
CAUTION
Do not exceed 2000psi hydraulic pressure when positioning the boom or mast for
recovery winching operations. The terrain can vary from muddy to hard pack making
specific boom and mast positions difficult to dictate. Limiting hydraulic pressure to
2000psi prevents damage to the equipment or injury to personnel from bursting lines.
4. Using the remote control, “EXTEND” the mast and insert the pivot pins, using the half hole rest, at
the second hole. (figure 2)

Recovery Winching with the FWTRD – Continued
NOTE
Keeping the fifth wheel section level keeps the FWTRD stable during winch recovery operations.
The booms may bury themselves into the ground as winching begins. Re-position the booms as
necessary to keep the fifth wheel section level, without exceeding 2000psi.
5. Using the remote control, “EXTEND” the booms until the transport legs clear the after frame of the
prime mover and the fifth wheel section is level.(figure 3)

6. Rotate transport leg handle counter-clockwise to raise transport legs. Secure with the small
bungee.(figure 4)

7.
Assemble rigging and connect winch cable to casualty in manner determined for intended recovery.
Refer to FM 4-30.31 for appropriate rigging techniques.
WARNING
All personnel must stand clear at a distance equal to the length of cable during
winching operations. A snapped cable or shifting load could strike personnel causing
injury or death to personnel.
8.
Disengage the winch free spool. Using the remote control, winch “IN” to remove most of the slack
from the cable.
9. Recheck rigging and then move all personnel to a safe distance
10. Commence winch recovery
11. Winch casualty to just in front of boom caps.

Recovery Winching with the XM20 FWTRD – Continued
WARNING
Prior to slacking the winch cable, the disabled vehicle must be secured from moving.
Failure to comply could result in the vehicle moving unexpectedly creating a crush
hazard causing serious injury or death to personnel.
NOTE
Rigging may or may not be removed from casualty depending on whether it is to be
lift/towed using FWTRD (remove rigging) or whether casualty is to be winched onto
TDRT in which case rigging would stay on casualty.
12. Remove winch cable. See note for rigging.
13. Using remote control, “EXTEND” the mast to release and remove mast lock pins
14. Using the remote control, “EXTEND” the boom to release and remove the boom lock pin.
15. Rotate the transport leg handle clockwise and lock the transport legs in the down position.
NOTE
If booms are severely buried it may be necessary to pull prime mover forward slightly to free
boom caps. Be sure there is enough slack in winch cable if you need to pull forward.
16. Using valve control levers “RETRACT” Booms to set the FWTRD on the transport legs, and to free the
Boom Caps.
17. Remove Boom Caps and stow in fifth wheel section.
NOTE
Proceed with securing the disabled vehicle for lift tow with the FWTRD, or position the Tilt Deck
Recovery Trailer (TDRT) for loading.
